Product Description:

Zinc formaldehyde sulfoxylate, commonly known as Rongalite or Decroline zinc, is a zinc salt of hydroxymethanesulfinic acid. It appears as a white crystalline powder and is a key reducing agent in industrial processes. Its primary and most significant application is in the textile industry as a discharge agent in vat dyeing and printing. It is used to create white or colored patterns on dyed fabrics by selectively reducing and removing specific dyes. It also serves as a reducing agent in the synthesis of certain chemicals and polymers, and as an antioxidant or stabilizer in some formulations. The compound is known for its strong reducing power under specific conditions (e.g., in alkaline media at elevated temperatures). It decomposes upon heating, releasing formaldehyde and sulfur dioxide, which necessitates careful handling and appropriate ventilation in industrial settings.
